BACKGROUND OF THE INVENTION

BACKGROUND ART Technical Field

This invention relates to a bicycle seat.

More particularly, the invention relates to a bicycle seat which comfortably

supports a bicycle rider without creating pressure on the perineum when the rider is

in any of several different positions on the bicycle seat.

Background Art

In a further respect, the invention relates to a bicycle seat which comfortably supports a bicycle rider when he is in an upright seated touring position with his

weight shifted to the rear, when he is in a performance position with his weight

shifted forward on the medial portion of the seat, and when he is in an extreme

forward position on the seat during a sprint.

In another respect, the invention relates to a bicycle seat which is specifically shaped and dimensioned to enable a rider to assume several different riding positions

in which the seat supports the rider without creating pressure on the rider's perineum.

A wide variety of bicycle seats are known in the art. There does not, however, appear to be a bicycle seat which is adapted to allow a rider to assume

several different positions in which the seat supports the rider without creating

pressure on the rider's perineum.

Accordingly, it would be highly desirable to provide an improved bicycle seat which would facilitate a bicycle rider's assuming several differing positions on

the seat while avoiding the creation of undesirable pressure on the rider's perineum. SUMMARY OF THE INVENTION

Therefore, it is a primary object of the invention to provide an improved bicycle seat.

Another object of the invention is to provide an improved bicycle seat which

permits a bicycle rider to sit in several different positions on the seat. A further object of the invention is to provide an improved bicycle seat which does not generate significant pressure on the perineum in any of the positions

which a bicycle rider can assume on the seat.

These and other, further and more specific objects an advantage of the invention will be apparent to those skilled in the art from the following detailed

description thereof taken in conjunction with the drawings, in which:

Briefly in accordance with our invention, we provide an improved bicycle seat. The

bicycle seat includes a support platform including a front portion, a medial portion, and a rear portion. The rear portion includes at least one raised portion for

supporting a bicycle rider's buttocks when the rider is in the touring position and the rider's tailbone is positioned over the rear portion. The medial portion includes a

recessed area and supports a bicycle rider's buttocks when the rider is in the

performance position and the rider's tailbone is positioned over the medial portion. The recessed area is shaped to avoid the production of pressure on the perineum. The front portion includes a spaced apart pair of converging arms for supporting a bicycle rider when the rider is in the racing position and the rider's tail bone is

positioned over the front portion. Each of the arms includes a feathered canted side surface for minimizing friction engagement of the front portion with the inner surface of the thighs of a bicycle rider when the rider pedals the bicycle. The bicycle seat also includes apparatus for mounting the seat on a bicycle.

In another embodiment of the invention, we provide an improved method for

traversing ground on a bicycle while in the touring, performance, and racing position. The method includes the step of providing a bicycle seat. The bicycle seat includes a support platform including a front portion, a medial portion, and a rear

portion. The rear portion includes at least one raised portion for supporting a bicycle

rider's buttocks when the rider is in the touring position and the rider's tailbone is positioned over the rear portion. The medial portion includes a recessed area and supports a bicycle rider's buttocks when the rider is in the performance position and

the rider's tailbone is positioned over the medial portion. The recessed area is

shaped to avoid the production of pressure on the perineum. The front portion includes a spaced apart pair of converging arms for supporting a bicycle rider when

the rider is in the racing position and the rider's tail bone is positioned over the front

portion. Each of the arms includes a feathered canted side surface for minimizing

friction engagement of the front portion with the inner surface of the thighs of a

bicycle rider when the rider pedals the bicycle. The bicycle seat also includes apparatus for mounting the seat on a bicycle. The method also includes the steps of mounting the seat on a bicycle; sitting on the medial portion of the seat while in the touring position; moving forwardly from the touring position to the performance

position; and moving forwardly from the performance position to the racing position.

In a further embodiment of the invention, we provide an improved bicycle

seat. The bicycle seat includes a support platform including a front portion, a medial

portion, and a rear portion. The rear portion includes at least one raised portion for

recessed area and supports a bicycle rider's buttocks when the rider is in the

performance position and the rider's tailbone is positioned over the medial portion. The recessed area is shaped to avoid the production of pressure on the perineum.

The front portion includes a spaced apart pair of converging arms for supporting a

bicycle rider when the rider is in the racing position and the rider's tail bone is

positioned over the front portion. Each of the arms includes a feathered canted side

surface for minimizing friction engagement of the front portion with the inner surface of the thighs of a bicycle rider when the rider pedals the bicycle. The bicycle seat also includes apparatus for mounting the seat on a bicycle. Each of the

arms can be inwardly resiliently displaced independently of the other arm.

BEST MODE FOR CARRYING OUT THE INVENTION Turning now to the drawings, which depict the presently preferred embodiments of the invention for purposes of illustrating the invention and not by way of limitation of the scope of the invention, FIGS. 1 to 4 illustrate a bicycle seat

constructed in accordance with the invention and generally indicated by reference

character 10. Seat 10 includes a front portion 13, a medial portion 12, and a rear

portion 11.

Rear portion 11 includes raised areas or plateaus 14 and 15 bounded by

generally planar surface areas 16 and 17. Surface area 26 extends between plateaus

14 and 15. Plateaus 14 and 15 can comprise soft pliable packets of gelatin, can

comprises soft resilient foam material, or can comprise any other desired material(s). Rear portion 11 also includes the back or end arcuate surface 62 of seat 10. The

distance over which the rear portion of seat 10 extends is generally indicated by arrows E. The back of seat 10 is indicated by reference character 62.

Medial portion 12 includes the C-shaped, arcuate, recessed surface area 18.

Area 18 partially circumscribes a part of the open area which extends through seat

10 intermediate arms 19 and 20. The medial portion 12 also includes a portion of arms 19 and 20 and of each of the feathered canted arcuate surface areas 21 and 22

on arms 19 and 20, respectively. As will be described, however, the primary

usefulness and function of surface areas 21 and 22 normally occurs when a bicycle rider is utilizing the front portion 13 of seat 10. The distance over which the medial portion of seat 10 extends is generally indicated by arrows F. Front portion 13 includes arms 19 and 20 and the majority of surface areas 21

and 22. Arms 19 and 20 include distal ends 23 and 24. Surface areas 21 and 22

need not be arcuate, can be flat, or can take on any desired shape and dimension as long as the function to minimize the contact of arms 19 and 20 with the inside of the

thighs of a bicycle rider using portion 13. The distance over which the front portion

of seat 10 extends is generally indicated by arrows G. The shape and dimension and

proportional relationship between portions 11, 12, 13 can vary as desired. FIG. 1

accurately represents the presently preferred proportional relationship between portions 11, 12, 13. Arm 19 includes upper generally planar surface 25. Arm 20 includes upper generally planar surface area 27. Arms 19 and 20 are substantially

rigid. However, arm 20 can be resiliently inwardly displaced in the direction of

arrow N independently of arm 19. Arm 19 can be resiliently inwardly displaced in

the direction of arrow M independently of arm 20. The distal ends 23 and 24 of arms 19 and 20 are not interconnected. Ends 23 and 24 can be inwardly resiliently

displaced a distance in the range of about one-sixteenth to three-sixteenths of an

inch. The resilient displacement of arms 19 and 20 is important in the practice of the invention because if a rider's left leg is, for example, displaced inwardly in the

direction of N against arm 20 while the rider is pedaling vigorously in the

performance or racing position, then the weight of the left leg bearing against arm 20

displaces arm 20 in the direction of arrow N to minimize the interference of arm 20 with the up an down movement of the rider's leg.

Presently, the length (indicated by arrows B) of seat 10 is in the range of

about 8.00 to 10.00 inches; the width (indicated by arrows D) of seat 10 is in the

range of about 5.00 to 7.50 inches; the distance indicated by arrows A is in the range

of about one to two inches; the distance indicated by arrows C is about 5.00 to 6.50 inches; and the distance indicated by arrows J is in the range of about 0.25 to 1.00

inch. The shape and dimension of seat 10 can vary as desired; however, the general

shape illustrated in FIG. 1 is presently preferred, as is the taper which is visible in

FIG. 1 and occurs from the rear to the front portion of seat 10. The opening which

passes completely through seat 10 intermediate arms 19 and 20 is important because it, along with recessed surface 18, functions to minimize or eliminate pressure on the

rider's perineum.

FIG. 2 illustrates a cross section of arm 19 along section line 2-2 in FIG. 1.

Arcuate downwardly canting surface area 21 can, if desired, be flat or convex instead

of having the concave curvature shown in FIG. 2. FIG. 3 illustrates a cross section of arm 19 taken along section line 3-3 in

FIG. 1. Arcuate downwardly canted surface area 18 can, if desired, be flat or convex

instead of having the concave curvature shown in FIG. 3. The shape and dimension of arm 2 is identical to that of arm 19. Arms 19 and 20 are generally symmetrical

with respect to the longitudinal axis of seat 10. The longitudinal axis of seat 10 is

coincident with arrows C.

FIG. 4 illustrates a cross section of seat 10 taken along section line 4-4 in FIG. 1. Plateaus 14 and 15 can be seen extending upwardly from generally planar surface area 17. Seat 10 need not, if desired, include plateaus 14, 15 and rear portion

11 can instead have a generally fiat upper surface.

The utilization of seat 10 to facilitate the movement of a rider 30 between several different positions on a bicycle 70 is explained with reference to FIGS. 5 to 7.

In FIG. 6, rider 30 is seated on bicycle 70 in a conventional performance

position with the tailbone of the rider 30 positioned over the medial portion 12 of

seat 10. The rider's tail bone is accordingly normally positioned and centered above one of the points which lies directly above line T2. The triangle in line T2 indicates

the point along line T2 above which the tailbone can be centered. When rider 30 is

in the medial position, the taper of arms 19 and 20 facilitates free movement of the

upper legs of rider 30 such that the rider's inner thighs do not unduly frictionally rub against the sides 63, 64 of seat 10. Arcuate recessed surface area 18 minimizes or eliminates pressure on the rider's perineum, as does the open area 65 intermediate arms 19 and 20. In the performance position, ore of the rider's weight is, in

comparison to the touring position, supported by the upper inner thigh and upper back of the thigh on each leg on either side of the perineum.

In FIG. 7, rider 30 is seated on bicycle 70 in a conventional touring position

with his weight shifted on the rear portion of seat 10 such that his tail bone is

positioned over the rear portion 11 of seat 10. The rider's tailbone is accordingly normally positioned and centered above one of the points directly above line Tl. The triangle in line Tl indicates one point along line Tl above which the tailbone

can be centered. The buttocks of the rider rest at least in part on plateaus 14 and 15.

Plateaus 14 and 15 and the rear to front taper of seat visible in FIG. 12 help provide

clearance for the inner thighs of the rider 30 while the rider is pedaling in the position illustrated in FIG. 7. The portion of opening 65 adjacent recessed surface 18, along with recessed surface 18, minimizes or eliminates pressured on the rider's

perineum when the rider is in the position illustrated in FIG. 7.

In FIG. 5, the rider 30 is seated on bicycle 70 in a conventional racing

position with the tailbone of the rider 30 positioned over the front or forward portion

13 of seat 10. The majority of the rider's tail bone is accordingly normally

substantially positioned and centered above one of the points which lies directly

above line T3. The triangle in line T3 indicates one point along line T3 above which

the tailbone can be centered. Opening 65 minimizes or eliminates pressure on the rider's perineum when the rider 30 is in the position illustrated in Fig. 5. In addition,

when the rider is in the position of FIG. 5 downwardly canted surface areas 22 and 21 facilitate free movement of the rider's legs during pedaling and facilitate

minimization of frictional contact of the rider's inner thighs with the seat during pedaling over ground 80. When the rider moves forward on the bicycle from the

touring position of FIG. 7 to the racing position of FIG. 5, the rider's upper thighs

tend to be positioned adjacent the sides 63 and 64 of seat 10 near the distal ends 23 and 24 of arms 19 and 20. Since the upper thighs flare, and normally are wider than the lower thighs, additional space facilitates the free movement of the upper thighs, "Feathering" or shearing off a portion of a conventional bicycle seat 10 to produce

the canted surfaces areas 21 and 22 fond in the seat 10 of the invention functions to create an additional "open area" (i.e. an area not occupied by seat 10) though which

the inner upper thighs can move without unduly frictionally contacting seat 10. The position of the rider's pelvis with respect to seat 10 when the rider is in the racing

position of FIG. 5 differs from the relationship between the rider's pelvis and the seat

10 when the rider is in the touring or performance positions illustrated in FIGS. 7 and 6, respectively. When the rider is in the racing position, the ischial tuberosities tend to be positioned laterally of surfaces 21 and 22 such that the lower ischial

tuberosities straddle and tend to lock or engage surfaces 21 and 22 of arms 19 and 20

intermediate said tuberosities. Even though the ischial tuberosities of the pelvis tend

to straddle arms 19 and 20 when a rider 30 is in the racing position, arms 19 and 20 are spaced sufficiently apart to prevent pressure from being applied to the rider's

perineum. Some minor amounts of pressure may be applied to the outer portions of

the perineum, but by and large arms 19 and 20 are shaped and spaced such that any pressure applied to the perineumis much less than that encountered in a conventional bicycle seat.

Alternate embodiment of the invention is illustrated in FIGS. 8 to 11 and

comprises a wedge shape seat 40 having a back 51, bottom 54, sides 52 and 53, a

front 46. Seat 40 tapers from back to front in the manner illustrated in FIG. 11.

Recessed surface areas 47 and 48 are shaped to receive the buttocks of a rider.

Ridge 43 extends intermediate surface areas 47 and 48. Generally, planar surface

area 41 extends between surface 47 and back 51. Generally planar surface area 42

extends between surface area 48 and back 51. Surface area 47 includes a canted arcuate wall or side surface 49 which in FIG. 10 extends downwardly from surface area 41. Surface area 48 includes a canted arcuate wall or side surface 50 which in

FIG. 10 extends downwardly from surface area 42. One important advantage of the

seat 40 is that seat 40 does, since it does not include a pommel, not produce any

pressure on the perineum. FIGS. 13 to 16 illustrate an alternate embodiment of the invention comprising a "ribbon" bicycle seat including rigid arcuate members 81 and 82

fixedly connected by the braces 83 and 84.

The seat of FIG. 1 has a length (arrows B) to width (arrows D) ratio in the

range of 1.00 to 2.0, preferably 1.4 to 2.0, most preferably 1.5 to 2.0. Further, the ratio of the width D at the rear of the seat to the width of arms 19 and 20 from the tip

of arrow M to the tip of arrow N is in the range of about 3.0 to 5.0, preferably about

3.25 to 4.00. The length of seat 10 is at least about ten inches. This length is necessary for a seat to have rear, medial and front portions which can accommodate

a rider's touring, performance, and racing positions. While the seat 10 can, if

desired, be longer than about ten inches, making seat 10 less than about ten inches long is not desirable.

When the seat 10 of Fig. 1 has a length B often inches, a width D of 6.50 inches, an opening 65 with a width A of 2.00 inches and a width J of .625 inch, and a width between arrow M and N of 1.75 inches, then seat can be used by and "fits"

over 90% of the adult population. As would be appreciated by those of skill in the

art, reducing the size of seat 10 for children and smaller sized adults and increasing the size of seat 10 for large adults is a straightforward readily accomplished matter. Extensive testing is not required. The criteria used to make larger or smaller seats

are those discussed above in defining the rear, medial, and front portions of seat 10

for the touring, performance, and racing positions of a rider.

A further embodiment of the seat of the invention is depicted in Figs. 17 and 18 and is generally similar to the seat illustrated in Fig. 1. In Fig. 17 seat 100

includes a rear portion 111 indicated by arrows El, a medial portion 112 indicated

by arrows FI , and a front portion 113 indicated by arrows Gl . Rear portion 111 of

seat 100 includes upper support surface 116 and back edge 162. Spaced apart arms 119 and 120 extend from medial portion 112. Arcuate concave surface 118 is

formed in the upper portion of medial portion 112. Arm 120 includes end 124,

elongate upper surface 127 and outer concave surface 122. The length Bl of seat

100 is presently preferably ten inches. The width Dl of rear portion 111 is six and one-half inches. The width Al of the portion of opening 165 in medial portion 112

is two inches. The width Jl of the portion of opening 165 near ends 123 and 124 is

0.625 inch. The length Cl of opening 165 is six and one-half inches. The width W

from the outside of the ends of arms 119 and 120 is about one and three-quarters inches.

The shape and dimension and size of seat 100 will fit comfortably over 90% of the adult population. Seat 100 (and seat 10) can, if necessary for children or

larger adults, be readily reduced or increased while maintaining the proportional relationships of the seat. For example, the proportional relationship of the length Bl

to the width Dl is about 1.5: 1.0. The proportional relationship of the width Al to

the width Jl of opening 165 is about 3.2.10. These proportional relationships, as

well as the other proportional relationships is seat 100, can be maintained when the size of the seat 100 is increased or decreased.

Fig. 18 illustrates one possible construction of seat 100 wherein seat 100 includes a plastic shell 190, a foam liner 180 shaped and dimensioned to contour and

conform to the top of plastic shell 190, and a vinyl or leather cover 170 which covers and protects foam liner 180 after liner 180 is positioned on shell 190. Wire bracket

200 is shaped to fit in the bottom of shell 190 so that shell 190 can be mounted on a

bicycle in conventional fashion. Shell 190 includes arms 119A and 120A. Arms

120A has concaved side surface 122 A. Opening 165 A is formed between arms

119A and 120 A. The shape and dimension of arms 119 A, 120 A, of surface 122 A,

and of opening 165 A is generally equivalent to the shape and dimension of arms 199, 120, of surface 122, and of opening 165 in Fig. 17.

Bracket 200 includes elongate parallel spaced apart base wire segments 205

and 206. Legs 203, 204, 207, 208 each depend from and are normal to either base

wire segment 205 or base wire segment 206. Foot 201 is normal to and outwardly depends from leg 203. Foot 202 is normal to and outwardly depends from leg 204. U-shaped member 209 interconnects and is attached to legs 207 and 208. The

distance, indicated by arrows K, between feet 201 and 202, between legs 203 and 204, and between legs 207 and 208 is one and three-quarters inches. The length, indicated by arrows L, of each base wire segment is five inches. While bracket 200 is substantially rigid, inward forces, indicated by arrows S and T, generated against

feet 201 and 202 or against legs 203 and 204 can inwardly resiliently displace feet

201 and 202 against each other. The construction of bracket 200 is important in the practice of the invention because feet 201 and 202 are spaced apart and are not connected to one another. This permits each foot 210 and 202 to move

independently of the other. This is important because foot 201 engages end 124 and

foot 202 engages end 123 of seat 100. Ends 123 and 124 are similarly spaced apart

and connected to each other and can move independently of one another. The ability of feet 201 and 202 to each be independently resiliently inwardly displaced toward and away from each goes hand-in-hand with the ability of each end 124 and 123 of

arms 120 and 119 to be independently resiliently inwardly displaced with respect to

the other end 124, 123. Arms 119 and 120 are preferably substantially rigid, but can,

as earlier noted, be inwardly resiliently displaced by lateral forces of the magnitude which commonly occur when a rider is in the racing position illustrated in Fig. 5, or,

when the rider is off seat 100 and is "standing" on the pedals of the bike and

pedaling with only the rider's inner upper thighs contacting arms 120 and 119. After

a compressive force generated in the direction of arrow S or T against an arm 201 and 202 is released, then arms 201, 202 (along with legs 203, 204 and segments 205, 206) and arms 119 and 120 return to their normal operative position illustrated in

Fig. 18. U-shaped member 209 generally prevents legs 207 and 208 from being displaced toward one another.

Having described my invention in such terms as to enable those skilled in the

art to understand and practice it, and having identified the presently preferred

embodiments thereof,

While particular embodiments of the present invention have been disclosed, it is to be understood that various different modifications are possible and are contemplated within the true spirit and scope of the appended claims. There is no

intention, therefore, of limitations to the exact abstract or disclosure herein

presented.
